Help with Uninstalling Avast

Tried to download Avast a few days ago, it was having troubles with completing download and creating troubles with me accesing my system settings. I am now trying to uninstall but that also wont work despire trying it through the uninstaller and through apple. Have been trying many things now and nothin seems to work. Rebooting etc… I am not very good with computers but have been looking online for help. I have been hacked so its important that i have software downloaded asap but now cannot download another one. Can someone please help?

You mention “apple”. So does this apply to a Mac or iPhone device?
If so, maybe best you post in the appropriate Mac/IOS section see:
